Maintenance has been completed, such as replacing the block capacitor and repairing poor main volume contact. A tubular mono power amplifier that makes you hear a profound, Macintosh sound. The sound has an air feel that is a bit different from the company's MC275. You can enjoy the relaxed and calm sound unique to vintage McKinn. This is a power amplifier I would like to try combining songs from yesteryear when I want to enjoy them with speakers from yesteryear. There are small scratches, dullness, etc. appropriate for the model year. (Oikawa Tetsuji)
